return doesn't work but cout does?

this function from my class returns the size of length of the linked list.

  int LinkedList::GetLength()
{
	int count = 0;
	Node* temp = head;
	while (temp!=0)
	{
		count++;
		temp = temp->next;
	}
	//cout << count;     <-- this works
	return count;
}

What do you mean doesn't work? Does the function not return the same value that is printed?

it doesnt return anything at all. just a blank space

That's impossible. It's returning an int, which will be 4 (or eight) bytes in size, and that memory will contain some value because it's impossible for it to not contain some value.

So what makes you think it's somehow a blank space?

Note that return doesn't automatically print the value. To print the value you need to do it explicitly.

 
 
cout << yourList.GetLength();
